The government’s net-zero noose draws tighter. At energy questions in the House of Commons on Tuesday, the Conservative MP Charlie Dewhirst asked the Energy Security and Net Zero Secretary Ed Miliband if the recent report by the National Energy System Operator (Neso) projected higher or lower bills under his policies. Miliband replied that Neso forecast lower overall costs. ‘It is completely logical to say that that will lead to a reduction in bills,’ he said.
Logic and historic data point in the opposite direction. Between 2009 and 2020, the average price of electricity sold by the Big Six energy companies rose by 67 per cent from 10.71p per kilowatt hour (kWh) to 17.92p per kWh. This wasn’t caused by any increase in the cost of natural gas. In fact, the average price paid by major power generators fell by 15 per cent over the period. There was, however, a spectacular explosion in the amount of wind and solar on the grid which rose from 4.5 gigawatts (GW) in 2009 to 37.95 GW in 2020.
The upward pressure on prices will only increase as Miliband pushes for more offshore wind. Earlier this week, the Financial Times reported a senior energy investment banker commenting on the hubris of the offshore wind industry, which has been hit by higher interest rates and supply chain inflation. Renewable energy projects require enormous upfront investment costs. The pay-off, its advocates argue, is that renewables have no fuel input costs. But it would be a mistake to assume they have minimal ongoing costs.
The North Sea is a harsh environment for wind turbines; fixing a defective wind turbine in the middle of the ocean is no easy matter. A 2020 forensic analysis of wind company accounts by Edinburgh University’s Professor Gordon Hughes found that Year 1 operating costs for deepwater wind projects averaged £44 per megawatt hour (MWh), rising to £82 per MWh in Year 12. Moreover, the output efficiency of wind turbines degrades at a rate of around 4.5 per cent a year. When plotted against the market price obtained for wind output, Hughes concluded that ‘a significant portion of wind output is expensive to produce and of no value in terms of its contribution to national wellbeing’.
Renewable subsidies are awarded in allocation rounds. The fifth allocation round (AR5), conducted under the previous government, was a dud because of rising project costs caused by higher interest rates and supply chain inflation. Coming into office, Miliband was determined to make a big splash with AR6. He threw bill payers’ money at it with a record-breaking £1.555 billion subsidy pot. The government accepted bids totalling 9.6 GW, which includes 5.34 GW of offshore wind and 3.29 GW of solar, capacity which is useless when it’s likely to be most needed to meet peak electricity demand on winter evenings.
